Promash help - boil length and color

[dachoe]

Is there any way to predict color after a long boil? By long boil, I mean like 3hrs. If I up the boil length, it just ups the preboil. It's my understanding that longer boils results in darker color, and wanted to see by how much color changes with longer boils.

I don't think it will change too much if you're brewing AG, although it will start out lighter because you'll have to dilute for more boil off. Why would you want to boil for 3 hrs? Even with a ton of pils malt in there, it's generally not necessry to boil more than 90 mins.

Help. I got a new computer and can't find how to unlock Promash. Are they still in business ?
